iroh ping
A very simple iroh protocol for pinging a remote node. It's a high level example & easy starting point for new projects.
Walk through the quickstart example in the Documentation Website.
Running the Examples
Quickstart Example
This example demonstrates basic ping functionality between two endpoints.
First, start the receiver in one terminal:
The receiver will print a ticket. Copy this ticket, then in another terminal run:
Replace <TICKET> with the ticket printed by the receiver.
Optional: push metrics to iroh-services
If the IROH_SERVICES_API_SECRET environment variable is set, the receiver will register with iroh-services and push endpoint metrics in the background. If it isn't set, the example prints a notice and continues without it.
Get a free API key at services.iroh.computer.
This is not the "real" ping
Iroh has all sorts of internal ping-type messages, this is a high level demo of a protocol, and in no way necessary for iroh's normal operation.
